Reaction Steps

A solution of 32 g. (0.098 mole) of 2-(2-dimethylaminoethenyl)-3-(4-methoxybenzoyl)nitrobenzene in 200 ml of ethyl acetate was treated with 5 g of 10% palladium-on-charcoal, and the starting material reduced with hydrogen under 50 p.s.i.g. The mixture was then filtered, the filtrate taken to dryness, and the residue recrystallized from ethyl acetate to give 18.1 g of 4-(4-methoxybenzoyl)indole. Another sample, similarly prepared by reduction of the starting material with Raney nickel in ethanol, afforded material having m.p. 148°-152° C.
